Julia Coulon/Tieche Seloncourt France/NY, b.1846

I'm looking for any information on Julia Coulon, aka Julia Tieche born in Seloncourt France in 1846, emigrated to the US as Julia Tieche. She had 4 children in total: Louis Coulon 1867, George Coulon 1871 and Helen Coulon 1878, and Jeanne Tieche in 1882.

She emigrated to NY through Ellis Island in 1906 as Julia Tieche with daughter Jeanne Tieche to live with her daughter Helen Coulon and son-in-law Daniel Burkholder. Also on the ship was George Coulon and his wife, Lena, and their son Frederick. These last are my great grandparents and grand father.

If anyone has any info on any of these people, please share, and i'll share what i have. Julia is a dead end for me, I am searching for any information on her first husband Mr. Coulon.
